7 piece set is made in the U.S.A., featuring SK's high polish SuperKrome® finish, which protects the tools from the harsh working environments found in today's workplace, while providing long life and maximum corrosion resistance. The SureGrip® wrenching design drives the side of the hex of the fastener, not the corner, to increase torque and avoid edge breakage, especially on rusted or damaged fasteners. Handle edges are rounded for improved gripping and increased user comfort. Set includes: 12 point flex combination wrenches - 3/8", 7/16", 1/2", 9/16", 5/8", 11/16" and 3/4".
